Abstract: A method, apparatus and computer program in which an apparatus exchanges wirelessly information with a public land mobile network. The apparatus detects a wireless device to device discovery initiation instruction from the public land mobile network and responsively: sends one or more wireless discovery signal transmissions for a peer device or to monitor wireless discovery signal transmissions sent by a peer device; and directly communicates wirelessly with a peer device that indicates having received the wireless discovery signal transmission or from which the apparatus has detected a wireless discovery signal transmission in result of the monitoring of wireless discovery signal transmissions.

Abstract: Methods, apparatuses, and computer program products for a mobile or roaming base station are described. An operating mode of a mobile base station is determined, based upon the mobile base station's current location and/or current mobility mode. The operating mode of the mobile base station is switched from a full base station functionality to a limited base station functionality, based upon the determining. A connection to a network is established by the mobile base station.

Abstract: Methods and apparatuses for handover of device-to-device (D2D) communications have been disclosed. A method may comprise: receiving, from a first device of a D2D cluster, a first measurement report which indicates a handover of the first device is needed; and determining, according to a D2D handover condition, whether to initiate or postpone the handover based on the first measurement report. In some embodiments, the first measurement report is sent by the first device in response to meeting the D2D handover condition.

Abstract: First and second level discovery messages for device-to-device discovery are determined to be going to be transmitted, resource(s) are requested for transmission of at least the second level discovery message, and allocated resource(s) of a second type are received. The first level discovery message is transmitted on either a selected resource of the first type or a selected one of the allocated resource(s). The second level discovery message is transmitted on a selected one of the more allocated resource(s) of the second type, A first level discovery message is received on a resource of either a first type or a second type. It is determined whether the received message is of interest or not and if the message is of interest, then it is determined whether a second level discovery message is available and if so, the second level discovery message is received on a resource of the second type.

Abstract: A user equipment UE has a c-plane connection to a macro cell and a u-plane connection to a source local cell. The u-plane connection is handed over to a target local cell while maintaining the c-plane connection so the macro cell can facilitate the u-plane handover. In one embodiment the UE uses coverage information about the source local cell and its own mobility to predict when the handover is needed, and the macro cell can identify which is the target local cell. The handover can occur across a coverage gap between the source and target local cells, where the UE gets synchronization information and a dedicated preamble for the target local cell prior to being in its range. In the examples also path switching and transfer of the UE context can occur prior to the UE being in range of the target local cell.
Abstract translation: 用户设备UE具有到宏小区的c平面连接和到源本地小区的u平面连接。 u平面连接被切换到目标本地小区，同时保持c平面连接，因此宏小区可以方便u平面切换。 在一个实施例中，UE使用关于源本地小区及其自身的移动性的覆盖信息来预测何时需要切换，并且宏小区可以识别哪个是目标本地小区。 切换可以在源和目标本地小区之间的覆盖间隙发生，其中UE在其范围内获得同步信息和目标本地小区的专用前同步码。 在示例中，UE上下文的路径切换和传送可以在UE处于目标本地小区的范围之前发生。

Abstract: An apparatus in a network node has circuitry configured for causing a scheduling of an uplink transmission for a first user equipment and a downlink reception for a second user equipment on at least one resource, wherein the at least one resource is at least partially shared between the first user equipment and second user equipment. The apparatus has circuitry configured for providing an instruction, to the first user equipment, to transmit a first signal within the at least one resource. The apparatus also has circuitry configured for providing an instruction, to the second user equipment, to detect the first signal within the at least one resource. The apparatus having further circuitry configured for receiving information, from the second user equipment, wherein the information includes an indication of whether the second user equipment has detected the first signal.

Abstract: Methods and apparatuses for enhancement of quality of service flows, for extended reality services or other services are proposed. For example, a method can include receiving a plurality of quality of service parameters for first packet-based communication. The quality of service parameters can include a packet delay budget for the first packet-based communication having a first end time. The plurality of quality of service parameters can further include a packet validity time for the first packet-based communication having a second end time equal to or later than the first end time. The packet validity time can be applicable to the first packet-based communication on a protocol data unit session basis, a quality of service flow basis, a set of protocol data units basis, or a packet basis. The method can also include transmitting the packet of the first packet-based communication to a further communication device.
